I posted the question on 1911 forum but thought I'd post it here as well.

I recently bought an interesting gun, a Colt .45 kit with extended Bomar rib. I know that those kits were shipped to Gil Hebard (but mine wasn't because the S/N ends with B, not H) and AMU smiths (but AMU smiths wouldn't put an extended rib on it, would they?). The MSH has a stippling job which looks very much like Jim Clark, but there are no other Clark markings on this gun, and the front strap is smooth. So I'm wondering if anyone here has or seen something similar?

Also, how do I rotate and remove the bushing when I need to disassemble it for cleaning? None of my bushing wrenches fit between the bushing and that extended front sight. Do I have to remove the rib (I would much rather not)?

I forgot to mention that the trigger (which looks like standard Colt short trigger) was also drilled and tapped for an overtravel screw, which is also what Clark used to do. I kinda want to think that he worked on this gun at least partially, but I can't find any of his markings anywhere on the gun.

Javaduke, These things are really rare and old so it would be very hard to set a price on it. How about 6 bucks and that includes shipping. I think flat rate mailers are 5.95 so I think I am getting a nickel for it. Sound fair?

Yours is the second 45 KIT slide I have seen. From the Gil Hebard catalog, only 1000 units were produced. You got a slide, barrel, and bushing. All oversize needing hand fitting.

Soon after, the USAMU had Colt machine 45 slides, drawing 7791435, which I believe is still current. They appear identical to the 45 KIT version.

The slides were marked on the slide stop side as NM7791435. Drake made the slide around 1965. Later, the military took bids for additional slides. I have several made by various vendors. Oh yes, the vendor ID is on the ejection port side. Often a line of letters and numbers. This is the CAGE number that you can look up on line. It is the vendor ID number.

The nicest ones I have seen are the IMI, Israeli Metal Industries, offerings. I have a brand new slide, barrel, and bushing made by IMI. Excellent workmanship.
